Hello. Am new to this site and looking for help on our Vita Spa. We recently drained it out, to add fresh water, and when we were setting the temp, the temp would not go up, despite our trying to hit the button several times. However it would work on lowering the temp. Now it sits at a cool 91 degrees. Is this a bad thermostat or just the button to increase the temp, bad?? It is a Selectron 200 and everything else seems to be working fine. We've even unplugged for a few and plugged back in, to maybe do a reset and same thing. Any help or suggestions would be appreciated!!
Too cool in my spa.....20150619_090159-1_resized.jpg
